This invention relates to polishes and particularly to a polish for automobile and other highly finished -surfaces.

The polish comprises water, mineral oil, 5 finely divided colloidal earthy material, an

abrasive and organic acids.

Any suitable mineral oil may be used. It is preferred to use a mineral oil such as straw oil together with a more viscous oil, such as a lubricating oil of viscosity about -85 sec. Saybolt at 100 F. It is preferred to use a highly treated or white oil since results are somewh at better than when a less treated oil is employed.

As the colloidal earthy material, wilkinite, bentonite, precipitated silicic acid or similar highly colloidal clay is preferred. As the abrasive it is preferred to use suitable earthy abrasive materials, such as infusorial earth, finely divided silica, or the like.

Various organic acids may be used such as oxalic, tartaric, acetic acid and other acids 'and hydroxy acids. It is, however, found that better results are obtained by using a mixture of oxalic and tartaric acids.

A polish according to the invention may suitably contain the following ingredients in the percentages by weight stated: Water 56 to 0.5%, infusorial earth 3 to 6%, oxalic acid 1 to 1.5% and tartaric acid 1 to 1.5%.
